Outline of Final Research Achievements

This study demonstrated that the effect of neural reconstruction in rat models. In control group (group A), buccal branch was compressed by a ligature clip at peripheral to bifurcation of mandibular brunch and mandibular brunch was cut and ligated. In groups B, C and D, the nerve reconstruction was made in a different manner. The method of neurorrhaphy were ‘end-to-side’(group B), ‘side-to-side (large window)’(group C) and ‘side-to-side (small window)’(group D) technique. Facial palsy score was assessed every week. We measured the count of neural cells at the facial nucleus and axons at the distal point of neurorrhaphy.
The result showed that group B was equal to group C and group D was inferior to B and C, and group A was worst score in all groups.
